Optimization of the make-up ball charge in a grinding

1992-3-1  The overall effect of a mixture of balls in the mill may be taken as the linear weighted sum (Austin et al., 1984e): L S, = Z mtSjj ( 14 ) /=1 L L Bi,= ( m,Sj.,Bo,l) / Z rnlSj.r (15) l=1 r=l The ball charge in the mill is split into L ball classes with diameters in a 4x/2 ratio, and mt is the relative mass frequency function of balls of size dr.

Ball Charge and Grinding Efficiency - Grinding ...

2021-5-5  Larger balls will increase P80 in ball mill, thereby reducing overgrinding. If you believe the entry ball size sets the initial point on ball population and exit size is fixed, since the ball wear is near linear, in some camps, this raises the P80 = can only result in grinding larger rock.

A population balance model of ball wear in grinding

2018-11-1  For this particular mill, we suggest a ball recharge of 0.005 balls / hour for the balls with diameters of 30.7 mm and 26.9 mm, while for balls with diameter of 40.5 mm, we suggest a ball recharge of 0.01 balls / hour. From the mill media wear rate obtained experimentally we analyzed the ceramic ball consumption C D SS.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space; Add to this another 10%-15% above the ball

Mill Charge - an overview ScienceDirect Topics

It is also similar to a ball mill because it uses balls, usually ceramic ones having 5-15 mm in diameter. Because the motion of the balls is independent of gravity, an attritor can handle thixotropic materials and slightly higher viscosity of millbases, but the principle of action and type of forces operating are similar to those of the ball mill.

Ball Mill - an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

List Factors Affecting Grinding Ball / Media Wear Rate

2018-4-30  In addition to wear speed, ball size and recharge practice, charge volume, and feed rate are significant factors affecting the actual production wear rate. Wear speeds are largely independent of ball size and ball charge volume. The wear rate exponent for SAG milling was experimentally determined to
